The invention discloses a monitoring device and a method for an elevator control power supply. The invention does not apply excessive control voltage on the elevator control circuit when the fact that the power supply of a micro-motor which controls the elevator is increased or decreased is detected. The elevator control power supply monitoring device comprises at least two independent control power supplies arranged inside the elevator control cabinet, at least two monitoring circuits which are connected to the independent control power supply and monitor the increase or drop in the voltage of the power supply, an elevator control circuit which is used for outputting control information enabling the elevator to operate normally on the basis of the voltage monitoring result of the independent control power supply and an elevator power supply control circuit which controls another independent control power supply and is used for connecting or disconnecting the power supply of the elevator on the basis of the monitoring result of the voltage of the independent control power supply and the control information coming from the elevator control circuit.
